Numerical simulations of turbulent dynamos
Abstract
Using a periodic box calculation it is shown that, owing to helicity conservation, a large scale field can only develop on a resistive timescale. This behaviour can be reproduced by a mean-field dynamo with α and ηt quenchings that are equally strong and "catastrophic".
